LBE it known that i, Devin C. .GnisWoLD, e citizen ,of United Stetesoilnmerce, residinget hl ort); Wilbrehem, in the county of 'Heinpden endStets of Massachusetts, have mvented new end useful improvements in lciten-Bening Devices, of .vhiclL the following is e speciieetion.

This invention reletes to improvements in step bearings and Ineens foredusting the seine, also in .means iorlree ing t e bearings thoroughlylubricated at e times; y

The object of the invention is to provide e device or mechanisnrthetwill readily een mit e vertical shaft (on the upper end of which islocated e. beveled gear) to be readily reised end lowered in order thatthe gears may properly mesh with each other et ell times.

A further object ofthe invention is to provide e. device theftI willreedily errnit the vertical bearing boxes to be reedi y removedoredjusted Without dismantling any part of the machine to which theimprovement is ap lied.

urther objects of the nature and conv struction of the invention will.be set forth in detail in the specification and clearly pointed out inthe claims.

In the drawings forming port oi this application-Figure 1 is e planvieiv of my inlvention showing the vertical she-it in section andclearly indicating the menner end Ineens for ed'ustino the boerin boxes.Fig. 2 is e pertiel vertical longitu insl sectonei 'View on line 2-2,Fig. Fig. 3 is e detail perspective view of the ediustin wedges end thebearing block orstep-piece oceted thereon. Fig. 4 is e. detailperspective view of one ci the bearing boxes, clearly showing thecutoutor rectangular portion for receiving the step-bearing piece.

Referring to the drawings in detail, c designetes the beso portion of myimprovement end l) the vertical side Wells oi my device which constitutea receptacle ior holding e suitable liquid lubricant, as indicated et c.The opposite ends of the side Wells are provided with adjusting screws dend lock-nuts e. These screws are threaded into the wells o and engagethe opposite ends oi the Wedge element f which is provided on its bottomsurface with parallel ribs g for allowing the oil to freely circulatefrom one end of the casing to Vthe other.' Located on the wedge f is eblock h valso Wedge-shaped 'in ilorin the inclination being such thatits upper surface i will be horizontal when in place.

y' designates the step or bearing piece, rectangular in form, forreceiving the lower end ci the verticel shaft k. The upper surface ofthis bearing piece may be eitherl curved, esshown et m or perfectlyliet.

in order to properly maintain the shaft lc in vertice-l elinement, thebearing boxes n end o are provided,-e detail view of one being shown hiFig. 4,-tl1e curved surfaces p oi which receive the curved suriece oithe elicit The bottom portion of these beering boxes is out out so as toform e rectangu- `ler opening g which, in the bottom portion of eachbearing box receives the rectangular step besring element j, es clearlyshown in the assembled view in lli 2.

Verticelly arranged plates r and s are placed against the outer surfaceofthe beering boxes n and o end ere edjus't'ebiy held in place againstthe shaft .7c by ineens of the horizontally disposed wedges t end uwhich are reteined in openings c and w in the side wells'l) oi' the oilreceptacle. The location of the Wedges t end u is cleerly indicated inFig. 2. When the bearing boxes n and o become Worn it is only necessaryro slightly drive the wedges and u, inward whereby the verticellyarranged pistes 1 end s ere moved against the boxes r1, and o towardsthe shaft' ic, end any weer or lost motion is thus teken u es readilyunderstood. When the teeth oi the gears 9: sindy become Wornso thatthere is danger of the seme being broken, ve# ceusetliey do not properlymesh; it is only necessary to loosen or turn back the screwd on theleft-hond side end turn forward the screw d on the right-hemd side ofthe casing so that the Wedge di" 'will be moved toward the left and theblocks .li and y' eleveted which, in turn; will elevate the streit 7cand bring the gears together so that they will properly mesh. Theoperation o1" replacing the shaft lc or the boxes n end o when the semehave become badly worn necessitates simply 'removing the Wedges i andU-,tlius permitting without disturbing the shaft .2; since thisoperation clears evv'ey ell of the obstructions,

seme manner. v l

it will be observed that the Wedel; efre oerried inward towers tireshaft ls, es shown in the plete s and the box o to be drefwn ewey i theshaft ic een than be teken iv/'ey vin tlie- Fig. l at b1, in order toafford a bearing for the side portions of the bearing boxes n and o.

One of the im ortant features of my invention is in provi( ing for thethorough lubrication of the shaft 7c and its engagement with thebearing-block 7L since the lower end of the shaft rotates at all timesin a receptacle containing oil.

This invention is particularly designed and adapted for use inconnection With paper or pulp-beating engines and is particularlyadapted to vertically adjust the shaft 7c and placing new bearing boxes;it is not necessary to dismantle the machine at all in order to makethese improvements or repairs(4 This invention also permits the verticalshaft k to be readily adjusted, as described in detail, which is a greatadvantage when applied to paper pulp machines.

What l claim, is

1. In a shaft-adjusting mechanism, in combination, a casing, a' ribbedWed e'- shaped element located therein, means.- or adjustably clampingthe same to the casing, a second Wedge-shaped element h mounted on thefirst Wedge-shaped element, a bearingblock j mounted on the element 7Lfor receiv-v ing the lower end of a shaft, as 7c, boxes n and o engagingsaid shaft, said boxes having a rectangular recess to receive the blocky', and means for adjustably securing the boxes 'n and o, to the casing,the ribbed Wedge-shaped element constitutlng means t0 permit the freecirculation of oil in the casing as described. l

2. In comblnation, a casmg provided With openings in the side portionthereof, a wedgeshaped element provided with ribs or grooves on itsunderside, a second Wedge-sha ed element located on the first mentionede ement,

a bearing-block mounted on the said second element, bearing-boxesinelosing the bearingblock and providing bearing means for a Verticalshaft, locking means for the bearing-
